Human papillomavirusassociated cancers as acquired immunodeficiency syndrome defining illnesses.

The Centers for Disease Control currently report cervical, vulvar, vaginal, anal and some head and neck cancers as human papillomavirus (HPV)-associated cancers. Only cervical cancer is listed amongst acquired immunodeficiency syndrome (AIDS) defining illnesses. All of these cancers may represent progression of the immunocompromised state with the inability to eradicate viral infection. This study reports the case of a 27-year old HIV positive female presenting with a persistent right vulvar exophytic lesion. High-risk HPV analysis and immunostaining for P16 were both positive. A biopsy of the lesion revealed invasive squamous cell carcinoma. The patient underwent neoadjuvant radiation and chemotherapy followed by a radical vulvectomy. During treatment, her CD4 T-lymphocyte count decreased to 120 advancing her condition from HIV to AIDS. This case suggests that all HPV-associated cancers should be included as AIDS defining illnesses.
